YOU’LL NEVER GET ONE OF 89 PAIRS OF ‘BACK TO THE FUTURE’ SHOES

WE KNOW, WE know: we’ve been a little excited lately about the HyperAdapt 1.0, Nike’s first-ever “adaptive fit” sneaker that tightens and loosens to your foot with the push of a button. But before the HyperAdapt, there was the Nike Mag, the movie-prop high-top that debuted back in 1989’s Back to the Future 2 and inspired Nike’s designers and engineers to work for more than two decades to make power-lacing a reality. Now that Nike’s finally done it and the HyperAdapt is hitting stores next month, the company announced today that it has created a limited-edition line of fully functioning Nike Mags, all of them equipped with adaptive fit technology, that it will raffle off to benefit The Michael J. Fox Foundation for Parkinson’s Research.

Nike has created replica Mags in the past, but none of them have come equipped with an adaptive fit. (As reported in our October cover story, the lacing system on the original Nike Mags were “powered” by crew members who literally pulled some strings to make the shoes tighten and loosen.) After all, that technology didn’t actually exist until Nike’s engineers, led by senior innovator Tiffany Beers, invented it for the HyperAdapt. But these new Nike Mags incorporate the same lacing engine and the same rechargeable lithium-polymer battery as the HyperAdapt, but they still look exactly like the shoes that Fox wore in BTTF.

Nike has produced a mere 89 pairs in a variety of men’s and women’s sizes, and most of them will be available only to those who purchase tickets online ($10 a pop) to enter a randomized digital draw (a raffle!). Buy as many as you can afford—all the proceeds go to finding a cure for Parkinson’s Disease, and the more you buy, the better your odds of nabbing a pair.
